ABSTRACT:
An improved stator structure for industrial cooling fans includes silicon steel plates punched directly into shape to allow direct magnetic conductance so as to enhance field intensity. Upper and lower silicon steel plates are passed through plastic insulating packing pieces and inserted into recessed grooves of a plastic sleeve. The assembly is then riveted in tight fit to achieve a motor stator structure.
